[PATCH 1/3] kobject: Add a jump label in kobject_uevent_env()

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Tue, 19 Dec 2023 14:16:35 +0100

Use another label so that a call of the function “kfree” can be avoided
after a failed call of the function “kobject_get_path”.
